GARPET-SWEEPER.

Specification of Letters Patent.

Patented June 8, 1909.

Application filed. November 20, 1908. Serial No. 463,665.

To all whom it may concern:

Be it known that I, FREDERICK GOE- RINGER, a citizen of the United States, and resident of Wilkes-Barre, county of Luzerne, State of Pennsylvania, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification.

This invention relates to improvements in carpet sweepers and particularly to improvements in that class of sweepers represented by Letters-Patent No. 738,919 granted to Andrew V. Fedor, in which a series of beaters are mounted in the frame of the sweeper and are adapted to beat the carpet as the brush travels over the floor.

The invention will be described in detail in connection with the accompanying drawing, in which,

Figurel is a section on the line 11 of Fig. '2; Fig. 2 is a bottom plan view of a machine embodying the invention; Fig. 3 is a perspective view of a part of the core of the brush and attached tappets for operating the beaters; Fig. 4 is a similar view illustrating 0113 of the hooks for holding the beater pivot r0 Referring to the drawing, 10 indicates a casing which the various parts are mounted and which may be constructed of wood or metal as desired. As shown the casing is constructed of sheet metal. The casing is supported on wheels 11, 12, mounted on shafts 13, 14, in the usualmanner. A rotary brush 15, is supported on suitable bearings 16 and rotated by rollers 17 which are engaged and driven by the peri heries of the wheels or rollers 11, 12. T e sweeper is also provided with pans 18, 19, which are pivotally supported and are adapted to receive the dust swept up by the brush. As shown a s ring 20 is connected with the pan 19 and a evice 21 is provided for dumping the an.

T e parts above described may be of any desired construction as they are not included in the present invention, which relates to the beaters and the means for operating them, which will now be described. I

I preferably provide the sweeper with a plurality of beaters and operate the same in succession by devices connected with the brush. As shown in the drawing, there are three beaters each having three arms or branches 22 which come in contact with the carpet and an arm 23 which is operated by tappets 24 which are pivotally connected to the rotating brush. As shown, the tappets 24 are pivotally mounted on staples 25 which extend across grooves 26 in the cylinder or core 27 of the brush, the inner ends of the tappets being arranged to work in the grooves which serve in a measure to guide them and cause them to swing in planes at right angles to the axis of the brush. The tappets are pivoted so that when the brush is run backward they will not operate the beaters, but will readily pass the beater arms 23. Each of the branches or arms 22 of the beaters is pivotally connected with a rod 28 around which they swing and the beaters are normally pressed downward by springs 29 which, as shown, are coiled about the rod 28 and have parts bearing on the beaters and on the frame of the machine. The rod 28 is removably held in the frame, its ends being mounted in loops or hooks 30 Figs. 2 and 4 at the ends of the frame and its middle portion being supported in one or more hooks or loops 31 Figs. 1 and 2 attached to the side of the frame. The springs 29 serve to hold the rod 28 in the loops or hooks 30, 31, but by applying sufficient pressure to bend the springs the rod 28 and the boaters may be readily removed from the machine.

It is sometimes desirable to throw the heaters out of action, as for instance when it is only desired to remove surface dirt from a carpet or to sweep a surface which does not require beating, such as wood or linoleum. For this purpose I provide a bail 32 pivotally mounted in the ends of the case 10 and extending under the arms 23 of the beaters. A suitable handle or crank arm 34 is provided on one end of the bail for turning it. When the bail is in the position shown in Fig. 1, the beaters are adapted to be operated by the tappets 24, but by turning the bail the beaters may be raised out of the path of the tappets and away from the surface upon which the sweeper rests, and thus rendered inoperative.

It will be evident that my invention, as hereinafter defined in the claims, may be embodied in various forms without departing from the spirit and scope thereof. The form illustrated in the drawings is the best now known to me and is very efiicient, and at the same time simple and cheap to manufacture.

Having described my invention what I claim and desire to secure by Letters-Patent 1s,

1. In a carpet sweeper, the combination With supporting wheels and a rotatable brush, oi' beaters arranged to operate automatically as the sweeper is moved over the surface upon which it rests, and means for rendering said heaters inoperative.

2. In a carpet sweeper, the combination with a casing, supporting wheels, and a rotatable brush operatively connected with said supporting wheels, of heaters mounted in the casing, means driven by said supporting wheels for operating said heaters, and means for rendering the heaters inoperative at will.

3. In a carpet sweeper, the combination with a casing, the supporting wheels, the retatable brush driven by said supporting wheels, and the tappets mounted on said brush, of heaters mounted in the casing and having parts extending toward said tappets, and means for throwing said parts into and out of the path of the tappets, whereby the heaters may be rendered operative or inoperative at will.

4. In a carpet sweeper, the combination with a casing, supporting wheels therefor, a rotatable brush and pivoted tappets mounted on said brush, of heaters pivotally mounted in the casing and having parts extending toward said tappets, and means for throwing all of said parts into and out of the path of said tappets at will.

5. In a carpet sweeper, the combination with the casing, the supporting wheels and the rotatable brush, of a series oi heaters, means for operating said heaters from the retatable brush and a hail extending under the heaters and adapted to raise them and render them inoperative when turned.

6. In a carpet sweeper, the combination with a casing, supporting wheels, and a retatable brush, of a rod extending lengthwise of the casing, a series of heaters pivotally mounted on said rod and adapted to be operated from the brush, springs mounted on. the rod and bearing upon the heaters, and means [or raising the heaters against the tension of the springs.

7. In a carpet sweeper, the combination with a casing, supporting wheels, and a retatable brush, of a series 01 heaters adapted to be operated from the brush, the said heaters being pivotally mounted upon a rod and said rod being detachahly mounted in the casing.

8. In a carpet sweeper, the combination with a casing, supporting wheels, and a retatable brush, of a series ol heaters adapted to be operated from the brush, the said heaters being pivotally mounted upon a rod, springs mounted 011 said rod and tending to hold the heaters down upon the surface to be beaten, said heaters, spring and rod being removably mounted in the casing.

9. In a carpet sweeper, the combination with a casing, of a rod removahly mounted therein, heaters pivotally mounted on said rods, and springs coiled about the rod and adapted to operate the heaters in one diree tion, said springs also tending to hold the rod removahly in the casing.

10. In a carpet sweeper, the combination with a casing, of a rod mounted in the casing, a series of heaters each having a plurality of arms pivotally connected to said rod, springs coiled about the rod and adapted to throw the heaters against the surface upon which the sweeper rests, and means for sustaining the heaters above the surface in inoperative position.

In testimony whereof I a'llix my signature in presence 01' two witnesses.
